The 718 Boxster PDK offers optional Porsche Active Safe, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The TT doesn't offer collision warning or crash mitigation brakes.

Both the 718 Boxster and the TT have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.

An engine control system that can shut down some of the engine’s cylinders helps improve the 718 Boxster GTS 4.0/Spyder’s fuel efficiency. The TT doesn’t offer a system that can shut down part of the engine.

Regenerative brakes improve the 718 Boxster’s fuel efficiency by converting inertia back into energy instead of wasting it. The TT doesn’t offer a regenerative braking system.

Regardless of its engine, the 718 Boxster’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The TT RS doesn’t offer an automatic engine start/stop system.

The 718 Boxster’s optional fuel tank has 2.4 gallons more fuel capacity than the TT (16.9 vs. 14.5 gallons).

For better traction and acceleration, the 718 Boxster has larger standard rear tires than the TT (265/45R18 vs. 245/40R18). The 718 Spyder RS’ rear tires are larger than the largest rear tires available on the TT (295/30R20 vs. 255/30R20).

The 718 Boxster has a much larger trunk with its top down than the TT Roadster (9.6 vs. 7.5 cubic feet).

To make loading groceries and cargo easier when your hands are full, the 718 Boxster’s available trunk can be opened just by holding your hand near the emblem on the trunk, leaving your hands completely free. The TT doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

When three different drivers share the 718 Boxster, the optional memory system makes it convenient for all three. Each setting activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle and climate settings. The TT doesn’t offer a memory system.

The 718 Boxster’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The TT doesn’t offer an easy entry system.

The 718 Boxster’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The TT does not have an oil pressure gauge.

In case of a sudden change of weather, the 718 Boxster has a standard remote convertible top that can be raised from a distance to protect the interior of the vehicle from damage. On a hot day the 718 Boxster has a standard remote opening feature, to lower the top from outside. The TT doesn’t offer a remote top, so the driver will have to run to the car, get in, turn the ignition on and raise the top to prevent the interior from being damaged.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The 718 Boxster has standard headlight washers to keep headlight output high. The TT doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors available for the 718 Boxster detect other vehicles which could be blinded and automatically switch to low beams. The TT doesn’t offer automatic dimming high beams.

The TT’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The 718 Boxster’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

Optional air-conditioned seats in the 718 Boxster keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The TT doesn’t offer air-conditioned seats.

On extremely cold winter days, the 718 Boxster’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The TT doesn’t offer a heated steering wheel.

The 718 Boxster’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The TT doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the 718 Boxster (except Manual) offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The TT doesn’t offer an adaptive cruise control.
